Yokohama Hakkeijima Sea Paradise is the new generation amusement park located at the tip of Yokohama Bay. The land is approximately 24 hectares with a lot of nice spots in it, including the aquarium itself with over 500 different varieties of fish and more than 100,000 sea creatures. You can also see three-story aquarium with thousands of tropical fish. You can enjoy the aquarium by walking along the tunnel with an undersea-like view. Some nice amusements are dolphin show, and the BLUE FALL, the 107 meters free fall attraction and the first surf coaster in Japan.
Some restaurants, fast foods, and a shopping mall can be found as well, you can also rent a hotel room if you feel tired or want to enjoy the surroundings more. As for the entrance admission, you do not need to spend any money. Also take a note that the visitors are not allowed to drive a car or a bike so it will be a good place for the picnics or taking a walk.
I suggest you to go there by train. Hakkeijima Station on Seaside Line is the closest station and has a beautiful seaside scenery. You can drive car by Route 354 from interchanges of Metropolitan Expressway Wangan Line “Sachiura” Exit and Expressway Yokohama-Yokosuka Road “Namiki I.C.”, but remember on Saturdays, Sundays, tourist seasons and public holidays, the parking lots are congested.
Shinagawa Aquarium is located on the western edge of Tokyo Bay. About 100 species of creatures live in the 500-ton tank. You can see undersea life along the 22-meter funnel located beneath the tank with 180-degree view. There you may see long-tooth grouper, sea bream, and giant rays swimming around and above you. You can also see dolphin and seal attractions, LED illuminated jellyfish, and “Jewels of the Sea” with various coral reefs with a few beautiful fish swimming around them.
If going by train, Omori Kaigan Station on the Keihin Kyuko Line is the closed station, you can walk about 8 minutes to the land.
